 | Wu, Yong-Shi | Nonlinear Ŵ∞ current algebra in the SL(2,R)/U(1) coset model | We show that in the world-sheet SL(2,R)/U(l) coset model there exists a hidden nonlinear W∞ current algebra, which incorporates all higher-spin (s≥ 2) currents including the energy-momentum tensor. Our proof is based on a free-field realization of Woo in terms of two scalars, as well as an ele... | W-algebras; Coset model; World-sheet; String theory; Spacetime; Quantum currents | 1992-05 |

 | Wu, Yong-Shi | Matrix compactification on orientifolds | Generalizing previous results for orbifolds, in this paper we describe the compactification of the matrix model on an orientifold which is a quotient space Rd/G as a Yang-Mills theory residing on a quantum space. The information of the compactification is encoded in the action of the discrete symmet... | Spacetime; Orientifolds; Compactification; Quantum space | 1999-06 |

 | Wu, Yong-Shi | Towards a noncommutative geometric approach to matrix compactification | In this paper we study generic M(atrix) theory compactifications that are specified by a set of quotient conditions. A procedure is proposed which both associates an algebra to each compactification and leads deductively to general solutions for the matrix variables. The notion of noncommutative g... | Matrix theory; Compactification; Noncommutativity; Orbifolds; Orientifolds; Spacetime; Klein bottle; Gauge theory; Torus | 1998-07 |
